Hi,

As a number of things depend on the logtransport.c split, I'd like to
merge that separately.

https://github.com/balabit/syslog-ng/pull/36

The branch itself is really just shuffling around files, basically the
monolitic logtransport.c that contained 4 classes were split into
separate files under the lib/transport subdirectory.

Thanks in advance.
